Because Central Asia is so cold, the people rely on culinary staples that are substantial and warm. The vodka helps, but a hearty root-vegetable soup like borscht gives the body a nourishing zip. First the beets are cooked whole to make a broth. Then other vegetables are added and all are cooked to make a colorful, richly flavored soup that gets even better the next day. To make cleanup easy, chop and clean the vegetables on a newspaper; to make the job faster, chop them in a food processor.
